Cataloging Accreted Stars within Gaia DR2 using Deep Learning

no code implementations15 Jul 2019 Bryan Ostdiek, Lina Necib, Timothy Cohen, Marat Freytsis, Mariangela Lisanti, Shea Garrison-Kimmel, Andrew Wetzel, Robyn E. Sanderson, Philip F. Hopkins

The goal of this study is to present the development of a machine learning based approach that utilizes phase space alone to separate the Gaia DR2 stars into two categories: those accreted onto the Milky Way from those that are in situ.

(Machine) Learning to Do More with Less

1 code implementation28 Jun 2017 Timothy Cohen, Marat Freytsis, Bryan Ostdiek

In this paper, we compare the standard "fully supervised" approach (that relies on knowledge of event-by-event truth-level labels) with a recent proposal that instead utilizes class ratios as the only discriminating information provided during training.
